5G, from the internet of people to "environment connectivity"

5G, from the internet of people to

Tomas Alonso, director of product engineering for Orange Espana

There is a lot of talk about 5G as something that comes and I think it's important to clarify what we're talking about.The first thing, I think, we can say is that is not a new technology as, in the past, we have been talking about 2G, 3G or more recently 4G, but 5G will be a new technological ecosystem that will change the rules of the game.

Actually It involves addressing a paradigm shift in mobile networks and, by extension, in the way of offering services to the general public and, for the first time, also in a massive way in many sectors of the industry.In the future, the main use of the network will not only be internet access, but multiple uses derived from the multiconexion d will appear e everything with everything, the "environment connectivity" we say in Orange.

development of virtual networks with 5G

In addition, 5G technology will allow the development of virtual networks adapted to each use case: bandwidth, latency, service differentiation in a world of millions of connected things.what we call "network slicing" We will therefore talk about vertical solutions (Energy, Automotive, Health, Media, Entertainment, etc.) that share one or more specific needs : critical processes in time, automation without time requirements, remote control, connections between companies or within companies and connected personal assets.

From a technological point of view, 5G offers three major quantitative improvement axes :

First greater capacity and greater speed .A x50 in speeds over the best current networks and a x10 in efficiency of use of the scarcer resource, the spectrum.

The second is its ability to have millions of connected things .From hundreds/thousands per km2 to millions.

And last but not least: a network of very high availability and ultra low latency (20 times less than today) that will allow us to also use very low power devices.

In summary, we are in a disruptive change regarding the capabilities we have known so far; we are talking about an end of the cycle (people's internet) and the beginning of a new era of equal or greater magnitude than the current one that will be the internet of connected things.

Well, all this is exciting, but when?

The 2019 will be a year of proofs of concept and pilots , but we can't pretend to start developing this technology with real use cases until 2020. On those dates In addition, events such as the Soccer Eurocup and the Tokyo Olympics are sure to catalyze the first commercial experiences of 5G and the paradigm shift involved.

The industrial telecommunications sector will continue to respond and transform society, and we will see if other industries are equally committed to the digital development of society.This will undoubtedly mark the "when" we will benefit as citizens of this evolution/revolution.

We are missing, finally, how to

Once clarified what and when, we just need to know how we will be able to build all this operators and the sector in general.

If I have to highlight technical success factors would be:

The development of virtualization .Allow me this word: "softwarization", which becomes the flexible partition of network functionalities for different needs. This will facilitate the programming of networks dynamically or digitally on demand of the use or the client.

New "Massive MIMO" antennas with ultra-narrow beams aimed at providing the coverage system, high speeds and capacity.Instead of the cell concept, which radiates at a frequency, these antennas they are going to offer us "capacity beams" with different characteristics according to the service we demand at all times.

This paradigm shift will require very high investments, which will not be sustained without a clear commitment to the digitalization of society, administrations and industry. Therefore, it is going to need the collaboration of all to make 5G possible and create the conditions that favor its development. Let's get down to work.

Internet of plants: a tomato knows as much about networks as you

The possibility of plant species communicating through complex networks, what some scientists have called the internet of plants , is an issue that has been discussed for a long time, at least 20 years.It was in 1997 when the scientist Suzanne Simard , from the University of British Columbia in Vancouver (Canada), published a study in the journal Nature on how Forest plants use complex systems where species exchange nutrients, send warning signals and relate to the environment. Although there is no scientific consensus, several investigations seem to support this hypothesis.If confirmed, as we read in a fascinating report by the Sinc Agency, the forests would act as huge structures that are articulated under the soil through a network in which factors invisible to the human eye interact and can determine the future of the climate.Understanding how it works is the challenge that even science faces. internet of plants and the wisdom of forests The premise of Suzanne Simard ...

New setbacks for conspiranoicos: radiofrequencies do not affect health

New evidence published by the Scientific Advisory Committee on Radio Frequency and Health (CCARS) in its 2016 Radio Frequency and Health Report indicates that there are no adverse health effects derived of exposure to radio frequencies emitted by mobile phone antennas or radio and television broadcasting.No evidence has been found on the danger in wireless systems (Wi-Fi) or airport scanners. The new 2016 Radio Frequency and Health Report collects, updates and analyzes the scientific evidence on the subject for the period between January 2013 and June 2016. radio frequencies are not dangerous According to the conclusions of the report " the critical analysis of the evidence supports that there are no technical or sanitary reasons that justify the arbitrary and discretionary imposition of more demanding exposure limits than those recommended by WHO-ICNIRP and the Union European ", while the application of more restrictive limits" would imply increasing the n...

GIF history: where they come from and where they are going

Funny, witty, curious... GIFs have already become a regular resource in social networks and messaging applications and have become part of our daily lives and jokes.It is an image format that has evolved significantly throughout its history and is experiencing a new awakening. In fact, to find its origins, we must go back more than twenty years ago .A moment in which they had little to do with what we know today and an evolution that we could not stop review.So let's find out where they come from and try to catch a glimpse of where they are going. What is a GIF The word GIF responds to the acronym of Graphics Interchange Format , or what is the same, graphic exchange format.A term for the graphic format used in the network for both static images and animations.In more concrete terms, it supports 8 bits per pixel and allows you to display images with up to 256 colors simultaneously-limited by a palette of 16 million-. This particularity makes it a perfect ally of infogr...

No kidding: selfitis exists and can be a problem

Sometimes one thinks that social networks were created to share photos of faces putting on little bones and images of dishes overflowing with appetizing foods or, better, of faces putting little bones in front of plates overflowing with appetizing foods in the same shot.is to see faces, faces, faces...all of them smiling, as if looking at the smartphone mirror was the height of happiness.And it does not seem that there are so many beautiful and happy people, or maybe yes, that you go Namely.What envy. Well, what we're going to do: Janarthanan Balakrishnan psychologists from the Thiagarajar School of Management in India; and Mark D.Griffiths, of the Nottingham Trent University, in the United Kingdom, have published an article in the International Journal of Mental Health and Addiction entitled 'A study on' Selfitis', which names this mania of going around the world taking pictures of oneself, as if beyond our curls the world had been destroyed by that meteorite th...

Twitter shows the best of ourselves (it wasn't always going to be the worst)

In the era of social networks, accustomed to interact daily with Facebook, Twitter, Instagram, Google or WhatsApp, we forget that these tools are phenomenal in the History of Humanity capable of mobilize hundreds of thousands of people in very different geographical locations in a matter of hours or even minutes. Already in the past, Twitter has asserted its more social dimension to mobilize people, companies or organizations and also, from a broader perspective, feelings of solidarity and support or also of rejection and repulses towards causes with an important mediatic impact.Recently, Twitter was once again the engine of solidarity after Dortmund's explosions as the Borussia Dortmund team bus passed on its way to the local stadium on the occasion of the Champions League match between the Borussia and the Monaco. These explosions did not have the devastating effect that they could have caused , so that everything remained in a major social commotion at international lev...

Most apps for children violate your privacy

Do you know if apps with which children enjoy their safety? A team of researchers from the International Computer Science Institute (ICSI) of the University of Berkeley has studied compliance with the Online Privacy Protection Act (COPPA) in these mobile applications for the little ones, through a scalable dynamic analysis that allows the automatic evaluation of privacy behaviors of Android apps. After studying 5,855 applications aimed at children, the research concludes that most of these apps, 57%, violate the privacy of their users mainly due to the use of data by third parties. apps for children and privacy Although many apps offer options in their configuration to respect the federal law that protects minors in the United States, by disabling tracking, their results suggest that a majority of applications either do not use these options or propagate them in wrong way. In addition, researchers believe that 19% of apps for children send user IDs to third parties to show ...

Are social networks damaging democracy?

The revelations according to which Russian agents inserted ads on Facebook that tried to influence the 2016 US elections raise a disturbing question: is Facebook bad for democracy? As an expert in the social and political repercussions of technology, I think that the problem is not exclusively from Facebook, but that it is much broader: Social networks are weakening some of the conditions that have historically enabled the existence of national states democratic. I understand that it is a dramatic statement, and I do not expect anyone to believe it immediately, but considering that almost half of all potential voters received false news promoted by the Russians in Facebook is an argument that must be debated. Associate Professor of Philosophy, Director of Center for Professional and Applied Ethics, University of North Carolina-Charlotte How we create a shared reality Let's start with two concepts: the "imagined community" and the "bubble filter". ...

This is how visual challenges star in some of the most viral content

Constantly, we all receive in our mail, our WhatsApp or our Facebook account, games that try to test our ingenuity, imagination or visual skill.There are a thousand types, more fun or darker.But they have one thing in common: we cannot avoid trying them and see if we are able to solve them .This is how the visual challenges star in some of the most viral content of the network. Visual challenges, why are we crazy? The visual challenges are games.So, they attend to this playful and fun part that people have no choice but to feed from time to time.They are pure and hard entertainment, with no more pretensions, and that desire to Having fun represents one of the main features that are sought when surfing the Internet . Another of the qualities for which they succeed is because they challenge the mind directly.Human beings love that feeling of feeling a little troubled, somewhat lost, but convinced that there is a solution to that enigma to which, sooner or later, it will come.Rathe...
